	Morphological Notes
	A11	Brigalow 4. Carbonate as soft segregations appears at 25cm and continues to 40. 
	Gypsum appears at 50cm and continues to 65cm, then in less quantity to 75. A 
	subrounded coarse quartz fragment 4-5mm diameter at 80cm is associated with a horiz
	A12	ontal band containing charcoal and scattered pieces of ? baked clay. One which I 
	cleaned and broke was angular, weathered, manganese-stained and sandy. This could 
	be a stratigraphic contact: is this a topsoil beneath younger material at 70c
	B21k	m? The soil at 70-80 seems also to have more pedality (a granular fracture) than 
	overlying material (a rough to nodular fracture). Note effervescence in fine earth, 10-
	20cm. Topsoil structure is ? subangular blocky. Very very few gypsum cry
	B22y	stals at 70-80cm, coarse fragments include subangular weathered sandstone. Very 
	very few gypsum crystals at 120-130, 250-260 in slickensided partings. 250-260 and 
	350-360 are noticeably dense and difficult to cut; 350-360 in particular. Roo
	2A1	ts are mostly on slickensided partings. Minor gypsum continues. Extremely tiny flecks of 
	red colour are seen from 5m on. They appear clearly at 480cm. One smaller coarse 
	fragment at 585 (subangular quartz). Hydromorphic mottles at 650-660 a
	2B21	nd 750-760cm in this core follow root and faunal passages infilled now with brown 
	(10YR5/3) and dark brown (10YR3/3) casts. At 750-760 the dusky red colour is 
	represented by clay skins. The occurrence of red stains in the clays above 620cm 
	3B24	horizon contains an inherited lithological discontinuity

	Site Notes
	The first hole on the transect that is in brigalow gilgai. Hole is 5m S of the road, among dense brigalow, on top of a gilgai mound.
	 Maximum relief is ~2m.
